CASH-REGISTER.

SPECIFICATION forming part of Letters Patent N o. '720.531, datedFebruary 10, 1903.

Application filed October 4, 1902. Serial No. 125,981. (No model.)

To @ZZ whom, it may concern:

Be it known that I, CARL LAURICK, a subject of the King of Prussia,German Emperor, and a resident of Berlin, in the Kingdom of Prussia,German Empire, have invented certain new and useful improvements incontinuous number stamping devices for cashregisters used for thecontinued numbering of checks, of which the following is a full, clear,and exact description.

This invention relates to improvements in cash-registers, and has moreparticular relation to improvements in printing devices for the same.

The object of the invention is to provide improved means whereby aconsecutive number or other data may be printed upon an insertedsales-slip.

The invention consists of certain novel constructions, combinations, andarrangements of parts, all of which will be hereinafter moreparticularly set forth and claimed.

In the accompanying drawings, forming part of this specification, Figurel represents a detail vertical section through the devices embodyingmyinvention, taken substantially on the line l l of Fig. 2, a number ofthe parts being indicated by dotted lines. Fig. 2 represents a detailplan view,partly broken away, of said devices. Fig. 3 represents adetail side elevation of the operating devices for theconsecutive-number printer, and Fig. 4 represents a transverse verticalsection on the line 4 4 of Fig. 2.

Describedin generalterms,this attachment, which is somewhat similar tothat covered by my United States Patent No. 707,603, dated August 26,1902, may be said to comprise a hinged lid or iiap which must be raisedin order to expose a reciprocating table or slipcarrier located belowthe same. The movements of this carrier after the flap has been closedeffect a feed of the printing devices for the consecutive number andfeed the endless inking-ribbon forward. The aforesaid printing devicesare carried eccentrically on y the said pivoted flap, so that when thesame is closed they Will impress the check or slip lying on the carrierbeneath them. As the means for operating the sliding slip-carrier formsno part of the present invention, I Will not describe the same, as anysuitable form of reciprocating mechanism maybe employed. One form ofsuch mechanism is shown in my aforesaid patent; but there are many otherforms which may be readily applied to reciprocate the'carriagepositively in both directions.

Described in detail, the frame l of the machine is formed on one sidewith a guidechannel 2, in which the slide 23 is arranged to bereciprocated by a hand-lever and connections of any suitableconstruction. yThis slide or carrier is formed with a table arranged toreceive the sales-slip, which is deposited thereon after the hinged Hapor cover 26 has been first elevated. This flap or cover is pivoted inthe main frame by trunnions 43, as best shown in Figs. 2 and 4, so thatit may be raised and lowered at will. A transverse shaft is journaledeccentrically in the cover or flap 26 and supports a series of nestedsleeves 53. These sleeves are provided at their opposite ends with` typewheels 52 and ratchet -Wheels 5l. The type -Wheels 52 are formed withnumeral-types for printing from zero to nine. These type-Wheels arearranged to be advanced upon each operation of the slide 23, so as toincrease the number to be printed by one. This advance of the type-wheelis effected by a plunger-rod 58, slidably mounted in the cover andpivoted at its forward end, as at 57, to an arm 56, which is journaledon the shaft 50. This arm 56 carries a pivot-pin 55, upon which aremounted a series of gravity-pawls 54,which are arranged to engage theirrespective ratchet- Wheels 5l. The extreme left-hand pawl 54 remainsalways in engagement with its respective ratchet-wheel, but theremaining paWls are only allowed to engage their respective Wheels whena transfer is to be made and are held out of such engagement by a seriesof guard-disks 82, connected to the respective ratchet-Wheels and uponwhich said pawls rest. Each of the guard-Wheels 82 is provided With anotch in its periphery, which permits its respective pawl 54 to dropinto engagement with its ratchet-wheelwhen a transfer is to be effected.As this transferring mechanism is old and well known in the art, nofurther description of the same is thought to be necessary here, itbeing sufficient to say that after the first ratchet-wheel at the lefthas made a complete revolution the second ratchet-wheel will be advancedone tooth, and so on through the series.

The ratchets are held against retrograde movement by a series ofspring-pawls 5l, mounted on the flap. The plunger 58 is normally held ina retracted position by a coilspring 59, mounted about the same andengaging with it'sopposite ends against a portion of the hinge-cover anda head 60 of said plunger. This head 60 engages an antifriction-roller63, mounted upon a bell-crank lever 64:, which is pivoted upon asuitable journal-stud extending from the main frame, as best shown inFig. 2. The lower arm of the bell-crank lever is engaged by the carriage23 when the latter is moved rearward, and the plunger 58 is thus forcedforward to cause the consecutive-numbering device to advance one number.The endless inking-ribbon 68 passes about the type-wheels 52 and oversuitable guiding-rollers to a feeding-roller 70, journaled upon the mainframe. This roller 70 is provided with a ratchet-wheel 69, which isengaged by a gravity-pawl 7l. The pawl 7l is mounted upon a slidingframe 72, which is mounted upon the main frame by screw-bolts 74, whichpass through elongated slots 73, formed in said slide. A spring connectsthe slide to the main frame to hold it in its normal forward position.When the carriage 23 is moved rearward, it engages a pendent arm 77 ofthe slide 72, and thus forces the latter rearward. This movement causesthe pawl 71 to feed the ratchet 69 forward one tooth, and thus feeds theribbon correspondingly. A pivoted pawl 76, mounted upon the main frame,engages the ratchet 69 to prevent any retrograde movement of the same.In order to hold lthe ribbon 68 taut, I provide a tension-roller 78,mounted upon an arm 80, which is normally drawn downward by a coilspring8l, connecting it to the main frame. The roller 78 rests upon the top oflthe ribbon 68, and thus takes up the slack in the same as the ribbonstretches.

The carriage 23 is provided with an impression-roller 67, upon which thesales-slip or check is laid when the flap 26 is elevated. When the flapis now closed, the type-Wheels 52 will because of their peculiareccentric mounting force the ink-ribbon against the slip or checkresting upon the roller 67, and thus make an impression. When thecarriage 23 is moved rearward, the check or slip remains stationaryagainst the type-wheels 52 until the platen-roller 67 has passed frombeneath the type-wheels. The pressure upon the check now being removed,it will travel rearward with the carriage 23.

It will be seen from the above description that th'e closing of the iiapor lid will effect the printing upon the check or slip, while therearward movement of the carriage with the slip will advance theconsecutive-printing device and feed the ink-ribbon.

I-Iaving thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination with a shiftable slipsupport, of a printing device,means for effecting an impression therewith upon the slip when the saidsupport is in its normal position, and means operated by theslip-support when shifted from such normal position, forv changing theadjustment of the printing device, substantially as described.

2. The combination with a shiftable slipsupport, of a printer mechanism,means for moving the printer and effecting an impression thereby, meansfor changing the adjustment of said printer by the shifting of saidsupport, an inking device, and means for operating said device by theshifting of the support.

3. The combination with a shiftable slipsupport, of a movable cover forthe same, a printing device actuated by the cover to make an impression,and means actuated by the shiftable support to change the adjustment ofthe printing device, substantially as described.

4. The combination with a sliding slip-carrier, of a pivoted coverthereover, a set of consecutive-numbering type-wheels mountedeccentrically to the pivot of said cover so as to effect an impressionupon a slip lying on the carrier when the cover is closed down, andmeans for changing the adjustment of the printer with each reciprocationof the carrier.

5. The combination with a sliding slip-carrier, of a pivoted coverthereover, a set of consecutive-numbering type-wheels mountedeccentrically to the pivot of said cover so as to effect an impressionupon a slip lying on the carrier when the cover is closed down, andmeans operated by the carrier in its reciprocations to change theadjustment of the printer step by step.

6. The combination with a slidable slipsupport, of a printing mechanism,aninkingribbon, a spring-drawn slide carrying a feeding-pawl andarranged to be operated by the slip-support, and means operated by thefeeding-pawl for moving the ink-ribbon forward.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

CARL LAURIOK.
